A lab rat is in a cell of a maze that has 2 doors to exit. The rat chooses a door at random with equal probability. If it chooses door #1, then it escapes the maze after one minute of travel. If it chooses door #2, then it is led back to the original cell after a random number of minutes that follows Uniform(0,8). If it returns to the cell, then it again chooses a door at random. If the rat chooses door #2 more than once, then the travel times are independent. Let X be the number of minutes it takes the rat to reach freedom. What is E(X)?
